vehicle so as to carry the wheels c the ground. A stop 13 is attachedto the bottom ofthe vehicle or to the chassis in any suitable manner, and the annular portion 5 8 of the leg is provided 'with' a lug 14- adapted to engage with this stop when the parts are brought to the position shown in Fig. 2, thus preventing any further rearward movement ot the lower end of the leg and holding it in proper vertical position.

In the form of my invention as shown in Fig. 3 pl provide means for latching the log, if desired, in its horizontal position or latching the leg in its vertical. position and for this purpose 1 provide a bolt 15 which is mounted in a bolt barrel 16, formed integral with'the leg. This bolt 15is adapted to engage in either one of the two recesses 17 and 18 formed in the disk 2 in quartering relation to each other and so disposed that the recess 18 is vertical while the recess 17 is horizontal and opens toward the trout ol the machine. The bolt 15 and its active end is so iFOll'l'ltd. as to enter the groove -l- 111 the periphery of the disk. 9 and thus form additional means for guiding the disk 2 with relation to the ring. A spring 19 disposed within the barrel acts to force the bolt 1 15 inward and the tension of this spring is 40 controlled by means of a removable plug or head 30, having screw threaded or other engagement with the outer end of the barrel 16. Preferably this head 20 has a bayonet joint engagementwith the end of the barrel 16 so that it may be held in place within the barrel by a hall" or quarter turn. When the head is removed from the barrel the spring or plunger will dropout. When, however, the head is in place the plunger or bolt 16 will be forced into engagement with the recesses 17 and 1.8. It will be understood that this device is only used tor looking the leg or supporting member in a raised position or for locking the supporting member in a lowered position when it is to be used as a jack, or permanent support 'for the car. It will be noted that the head or plug; 20 has a recess 21 in its under face l and it will be also noted that the web forming the opposite end of the leg or suport is likewise :t'orrnod with a recess 22, This is to provide means whereby aloclr may be inserted to hold the bolt 15 in cngagou'ient with either the recess 17 or the recess 18'. such a lock is illustrated in Fig. 41 as applied rounds the casing 33 ot the transmission to the construction shown in Fig. 23, and. inasmuch as this lock is fully described in my pending application for patent on bicycle locks, Serial No. 721,061, filed on the 18th day of Sept, 1912, it is not believed that any further description is necessary. This look includes a barrel 23 having oppositely disposed pins or bolts 21 adapted to engage respectivel i with the recesses 21 and. 253 and mounted upon the barrel of the loclrare a. plurality of rotatable tun'iblcrs 25 forming a combination lock, which when turned into a certain relative position will release the bolts or pins 2-1 and permit the lock to be removed, but which when turned into a err tain other relative position will prevent the release of the pins 24 from their engage ment with the recesses 21 and 2:3. It will be obvious then that when the loclr is in place,

the plug, or head 20 cannot be removed from its engagement with the barrel 16 and that as a consequence the bolt 15 will be held firmly in engagement with the dislril preventing any rotation of the leg or supporting member with relation'to the disk. .0

I. do not wish to be limited to the disposal of the lock 25 as illustrated in Fig. 4, as the loclr itsclt might be disposed between an intermed ate web 26 and the annular portion 8 oi the member '7, as illustrated in Fig. 6. This dispenses with the barrel in, the spring pressed bolt 15 and related parts. The ring is perforated as at QT, the web It is also recessed and the lOClt 25 is inserted between the web 913 and the ring 8. One of the pins or bolts of the lock projects into a recess in web 26 while the other projects into and through the pcrit'oration 27 and engages one or the other of the recesses 25) or 30 formed in the rim of the disk 31. The I web 26 is provided with a stud 28 adapted to be engaged by the lever shown in F i g. 8 for the purpose of manually forcing the logs into a supporting or vertical position. In the form of my invention shown in Fig. 5, the disk 31 is illustrated as formed with. a relatively thin web pierced at intervals so as to secure lightness, this web being formed with a-ccntral hub 82 which surshaft. In this form of my invention the disk 31 is termed with shoulders 31 and 35 which form stops limiting the arc of rot-ation of the leg or support 7, the ring 8 being provided with a lug 31) adapted to engage with either one of the shoulders or At a point coincident with the recesses 29 and 30 the disk is formed with enlarged portions 37 so as to strengthen the disk at this point. it is to be understood that the disk may be made slreletonic in form without departing in any way from he spirit of the invention. ln place of forming the ring 8 with the lug 36 as shown in Fig. (i, 1 may form the ring 8 with a 180 in con unction with sitely disposed studs 28 with which the gal hoolzs 44 engage. Thus in order to force the machine forward upon the legs, the lever is disposed with its hooks. rver the pins 528 and with the body of the lever hearing against the housing. 33. The upper end of the lever is then forced forwsrd the housmg acting as a fulcrum thus forcing;- the rotution of the ring 8 In an opposite .30 of the disk 31.

body of the vehicleiorward and the leg: into a vertical position; A reverse manner of using the lever will set to force the legs into a horizontal position. Preferably, however, I'provide the means illustrated in 7 for forcing the legs or supporting Blfilll bers either into a horizontal or a vertical position. To thisend, I form the ring 8 at its rear with a slotted protuberance 45, and dispose in this protuberance a rotatable member 46 interim-1y screw threaded. Pussing through this interior screw thread und into engagement with at stop 47 formed on the disk 41 is a screw l8. The screw 38 previouslydescribed not onlyperfornis tho. function of 'a stop screw, but is also long enough sothat it may be turned up and thereby rotate the ring 8 in one direction while the screw 48 will rotate the ring 8 direction. Normally, of course the screw 38 will be so adjusted that it will act as a stop. When, howev r it is desired to manually force the leg; or support downward into a, vertical position to thereby jack up the vehicle the screw is turned. This beuring'as it does against the abutment 4? or shoulder, will cuuse the l to be rotated irroni u. posi um such sl rovvn 5 such shown 111 in 3 to :1 position I Fig. 2? A rotation oi the screw will u in a reverse manner to rotate the legfrom the position shown in Fig, 2 to that in Fig. 3 and also the car onto its wheels. The

.screw 4-8 is an emergency screw and is of the screw threaded opening in therotatuble member 46. Otherwise it would prevent the upon the disk ll. in Fig. 6 I show-a means for holding the leg 7 in a horizontal position or locking it in a vertical position. This comprises the cotter pin elil'which passes through the opening in the outer ring and into the opening This pin 49 connected to a cord 50 which runs up in convenient position to the drivers hand. If it is decourse not intended to normally pass through comprises a handle through I sired to use the. emergency brake the cord 50 is pulled, pulling out the pin and permitting their-gs to drop us previtmsly (leseriherl. ll lieu the pin is imerictl us in Fig. it ass sts in locking the leg' 7 in a vertical. position. i

The operation of my invention is the some for all the various forms shown. ihc bracing or supporting members or legs 7 are held ruisod that is, in the position shown by dotted lines in Fig. lVhen it is desired to use the emergency brake the flexible con 'nection ll is loosened or the pin {l9 pulled out .YUClBIIlPUlJ. the legs or supports will hill to the position -l1l)- u in. 3-5 and the moineiurun oi, the Vchirle will carry the l s tfowjujwurd lo the pusuu 1 shown in I w. 2.,
